Tip: Trace the individual printed panels on the plastic sheet to ensure the size of the windows will fit between the printed sides. Once the lines are drawn, continue holding the ruler against the line to keep the lines straight.
Step 4: Now it is time to assemble the terrarium. Start by ensuring the flat side of the bottom support piece is facing down. Then, generously place hot glue on the outside ridges of the bottom support piece. Firmly attach the terrarium's panels onto each side by sticking the panels to the glue on the outside ridges until the terrarium is assembled.
